McCoole associate jailed over child porn

An Adelaide man who was a VIP member of the child pornography website run by notorious pedophile Shannon McCoole has been jailed for more than seven years.

David Glen Cecchin pleaded guilty to five child porn offences between 2012 and 2014, with his actions described as "prolonged, extensive and grave".

In the South Australian District Court on Tuesday, Cecchin was jailed for seven years and five months with a non-parole period of four years and six months.

When he was arrested in 2014 police found him to be in possession of 1500 child pornography images and videos.

But in sentencing Chief Judge Geoffrey Muecke said the full extend of Cecchin's offending might never be known as police had not been able to access some of his computers and hard drives that were protected by encryption.

The judge said Cecchin had also tried to minimise his offending and had told different stories to different people, painting himself as a victim of others who persuaded him to participate.

But Jude Muecke said it was difficult for him to put much confidence in anything the 30-year-old said about his crimes, and he remained unconvinced by Cecchin's claims that he wasn't really interested in child pornography.
